Hello, In my LocalSettings.php, I've put this : $wgGroupPermissions['user' ]['move'] = false; $wgGroupPermissions['user' ]['read'] = true; $wgGroupPermissions['user' ]['edit'] = false; $wgGroupPermissions['user' ]['delete'] = false; $wgGroupPermissions['user' ]['createpage'] = false; $wgGroupPermissions['user' ]['createtalk'] = true; $wgGroupPermissions['user' ]['createaccount'] = false; $wgGroupPermissions['user' ]['upload'] = false; $wgGroupPermissions['user' ]['reupload'] = false; $wgGroupPermissions['user' ]['reupload-shared'] = false; $wgGroupPermissions['user' ]['minoredit'] = false; $wgGroupPermissions['user' ]['import'] = false; $wgGroupPermissions['user' ]['protect'] = false; I thought ['createtalk'] = true; allow users to creation discution but it's not the case, did I mist something somewhere ?
